摘要:

制造了由LSO和LuAP晶体制成的晶体阵列(2 × 2 × 10 mm像素),用于评价具有相互作用深度(DOI)测定能力的探测器,该探测器预期用于小动物正电子发射断层扫描仪。研制了基于8 × 8晶体阵列和哈马松R5900-00-M64位置灵敏多阳极光电倍增管的位置灵敏LSO/LuAP Phoswich DOI探测器。时间分辨率被发现是不差于1.0 ns的FWHM的两个层,和空间分辨率的平均值为1.5 mm的FWHM的视场中心。

英文摘要:

Crystal arrays made of LSO and LuAP crystals 2x2x10 mm pixels were manufactured for evaluation of detector with depth-of-interaction (DOI) determination capability intended for small animal positron emission tomograph. Position-sensitive LSO/LuAP phoswich DOI detector based on crystal 8x8 arrays and HAMAMATSU R5900-00-M64 position-sensitive multi-anode photomultiplier tube was developed and evaluated. Time resolution was found to be not worse than 1.0 ns FWHM for both layers, and spatial resolution mean value was 1.5 mm FWHM for the center of field-of-view.
